Neutron stars (NSs) are perhaps the most interesting astronomical objects from the physical point of view. They are associated with a variety of extreme phenomena and matter states for example, magnetic fields beyond the QED vacuum pair-creation limit, supranuclear densities, superfluidity, superconductivity, exotic condensates and deconfined quark matter, etc.

The entrainment of superfluid protons by rotating superfluid neutrons leads to appearance of proton vortices and to generation of a homogeneous mean magnetic field with amplitude B and direction parallel to the axis of rotation of the star [20], This field will penetrate into the quark core through the normal cores of quark vortices. 

We shall consider the behavior of the magnetic field at distances r much larger than Ap and Aq. Also we take into account that Aq < Ap < a, Aq < p < R and q < Ar> < R — a. Therefore the components of the magnetic field in the different regions of neutron star are for r < a...

We assume that the stellar magnetic field is dipolar ( m d), and has axial symmetry everywhere. We use cylindrical coordinates (w,, z) centered on the neutron star and aligned with the stellar rotation axis. This configuration is sketched in Figure 1. We obtain the nondimensionalized equations which construct a complete set for the dynamics of reservoir ring, as following,...

Figure 8.6 A spinning neutron star (pulsar) appears from Earth to flash with a bright pulse of radiation that matches the period of its rotation. Charged particles near the star s surface rotate with the magnetic field and give off electromagnetic radiation.

Many neutron stars look like the drawing in Figure 1. The neutron star s rotation axis is inclined with respect to its magnetic axis. (The same situation prevails on Earth.) The neutron star s rapid rotation and intense magnetic field cause radiation to be emitted in narrow beams from the magnetic poles. If the Earth happens to be in line with one of these beams, we will see a flash every time the neutron star rotates and carries the beam past us. 

The discovery of very strong magnetic fields in compact galactic objects, namely white dwarf stars (see, for instance, the review of Garstang [1]) and neutron stars ([2] see also [3] and references therein) has led to substantial efforts to understand the electronic structure of atoms subjected to such fields.
